Contrary to previous SoCs, bcm2711 doesn't have a prescaler in the PLL feedback loop. Bypass it by zeroing fb_prediv_mask when running on bcm2711. Note that, since the prediv configuration bits were re-purposed, this was triggering miscalculations on all clocks hanging from the VPU clock, notably the aux UART, making its output unintelligible.

The YAML schemas that landed forgot one clock: "bi_tcxo". Presumably the bindings were developed against the v4 version of the driver and when the ".name" was removed in v5 of the driver things broke. While touching this, add the needed includes in each example. I believe both examples are supposed to be independent of each other. Let's fix the bindings.

For test and debug purposes, it's simple enough to enable or disable clocks from shell. Add a new debugfs file 'clk_prepare_enable' that calls clk_prepare_enable() when writing "1" and clk_disable_unprepare() when writing "0". This can have security implications, so only support it when the code has been modified to #define CLOCK_ALLOW_WRITE_DEBUGFS. Signed-off-by:

Jonathan Marek authored
Fixed ops were already identical, this adds support for non-fixed ops by sharing between trion and lucid. This also changes the names for trion ops to be consistent with the rest. Note LUCID_PCAL_DONE is renamed to TRION_PCAL_DONE because it is wrong for lucid, LUCID_PCAL_DONE should be BIT(27). Next patch will address this. Signed-off-by:

Reusing the generic struct vc5_hw_data for all blocks is handy. However it implies we allocate space the div_int and div_frc fields even for the output drivers where they are unused, and the clk_output_cfg0 and clk_output_cfg0_mask fields for all components even though they are used only for the output drivers. Use a dedicated struct for the output drivers so that each block uses exactly the fields it needs, not more. Signed-off-by:

When getting the names of the child nodes, kasprintf is used to allocate memory which is used to create the string for the node name. Unfortunately, there is no memory check to determine if this allocation fails, it may cause an error when trying to get child node name. This patch will check if the memory allocation fails, and returns and -ENOMEM error instead of blindly moving on.

There are a several places where printing an error message of init.name occurs after init.name has been kfree'd. Also the failure message is duplicated each time in the code. Fix this by adding a registration error failure path for these cases, moving the duplicated error messages to one common point and kfree'ing init.name only after it has been used.
